TE Connectivity's thermal and hydraulic magnetic circuit breakers

Image of TE Connectivity's Circuit BreakersTE Connectivity's thermal circuit breakers are available with rocker, push-pull, toggle, and push-to-reset actuators. These circuit breakers combine on/off switching with circuit protection in a single unit. They also offer a low-cost alternative to magnetic circuit breakers.

Magnetic Circuit breakers offer ratings from 20 mA to 50 A. Magnetic models are 1-pole to 4-pole devices. All series meet UL 1077 requirements, and several types meet ignition protection according to UL 1500.
